Abstract
The invention relates to a lap former (10) for producing cotton rolls (12). Cotton wool strip (14) is coiled on a bobbin (H) which is driven by one ring-moving drive belt (18) in the device, the bobbin can be rotationally located between two guide rollers (R1, R2) around a shaft (A), and a drive belt hanging ring (20) which can be gradually enlarged by the tension of a tension device (20) as the augmentation of the cotton rolls is allocated. The motion direction (F) of the drive belt (18) is at least guided in rigid connection in the regions of guiding roller (R1, R2, R3, R4) at horizontal direction.
Description
The present invention relates to a kind of lap former of producing lap, the cotton-wool bar is winding on the bobbin that belt driving belt drives by on this device, this bobbin is between two guide rollers, can pivot, and being positioned to increase along with lap, the driving belt pendant that is subjected to the tensioner tensioning also enlarges gradually.
From disclosed prior art, the described this device known to everybody of patent specification DE-A1-195 39 365 for example promptly is to use the driving belt that goes in ring to form a lap.This moment, the cotton-wool bar was fed in the middle of two guide rollers of driving belt pendant.Be contained in the supporting and can be positioned at the driving belt pendant by rotating bobbin, bobbin obtains frictional drive by the driving belt motion.When winding process began, the cotton-wool bar was fed into the zone between the inner face of bobbin circumference and driving belt pendant.The cotton-wool bar of feeding is wound on the bobbin with the belt transfer movement.From the bobbin radial direction, the wadding bar is wound up on the bobbin by this process stackedly.Use this lap former, can under high winding speed, form a lap very closely.But also demonstrate, each cotton layer fringe region fiber or the fibre bundle that stretches out partly occur and causes occurring in the lap end region interrupted whole surface thus.So not only make the lap outward appearance not beautiful, and combing machine add and also shortcoming can occur man-hour afterwards, especially appears at the subregion at the lap edge of debatching.
Producing these shortcoming main causes is, though driving belt has high tension force, in winding process, driving belt produces a kind of lasting and partly small side direction reciprocating motion.Because this being displaced sideways, the lap outermost layer is always done a little displacement to the following one deck cotton-wool on its bobbin.Especially lap edge zone of fiber is in this displacement movement, so very bad effect is played in displacement.Mainly be that fiber moves and separates from cotton layer China and foreign countries.In addition, this displacement can make lap produce ill effect in the debatching process on road, back combing machine, felting occurs between the promptly cotton layer.
Using under the dish situation of lap limit, this displacement is more apparent shortcoming in lap pendant zone.This is because the avris of a position moves, and spaces between lap and the avris godet and dwindles, and is folding thereby the lap fringe region may produce.
Task of the present invention is to get rid of above-mentioned shortcoming, and advises that a kind of can production has all lap formers of the lap at even clean and tidy edge.
The method that solves this task is, in the guide roller zone, driving belt at least by its direction of motion sidewards by guiding with being rigidly connected.This suitable guiding guaranteed driving belt in the guide roller zone at the horizontal acquisition settling position of its throughput direction, make each cotton layer on its desired location of bobbin width, the avris situation of movement take place no longer.
At least one side of suggestion driving belt should be convex-concave structure, and from the driving belt carriage direction laterally, this convex-concave structure constitutes rigidity guiding with having the guide roller outer surface of doing.This rigidity guiding can guarantee to stop being displaced sideways of driving belt in the deflector roll zone.
In addition as advise, from driving belt vertically and the circumferencial direction of guide roller see that this convex-concave structure has the shape of tooth bar.The i.e. concave surface of taking this convex-concave structure just to form the convex surface of channel form from vertically seeing of driving belt.For this reason, the convex-concave structure of driving belt and guide roller can be meshing with each other, and the tooth of this channel shaped and groove are the circumference that is arranged in guide roller with axially staggering.The form of spline-simulating can have different geometries.It is contemplated that driving belt and guide roller are that edge region has a kind of groove structure.But from the width of driving belt, groove-shaped also can be different geometries.
Suggestion as another kind of structure is, driving belt is provided with many eyelets, and by blanking time, the double wedge of deflector roll is engaged in the eyelet, here the double wedge of deflector roll circumferencial direction is to settle like this, promptly has at least a tooth to be in engagement when driving belt moves always.Driving belt is edge region and be vertically arranged with eyelet always, and the double wedge that is installed on the guide roller promptly enters in the eyelet.It is contemplated that in addition to be installed with these gears in the guide roller fringe region, their tooth is engaged in the eyelet of driving belt.This class guiding for example has use in the printing machine in non-field, guider to go in ring paper mold and is provided with gear in order to draw there, and it meshes with the eyelet of belt paper mold.
An imagination suggestion is again, and driving belt is intervally distributed with director element whole vertically being equipped with, and when driving belt moved, they connected each other by blanking time rigidly with the fixedly connected director element of guide roller.
Than the tool advantage, in order to make the driving belt both sides stable, use three guide rollers at least and carry out the rigidity guiding here by the suggestion driving belt through two above guide roller guiding for driving belt.In order to make the also stable and elimination movement clearance of driving belt avris guiding, the driven bobbin of special suggestion is to be supported rotatably around fixed axis.
Because what proposed installs drivable lap limit dish at driving belt pendant avris and combines with a stable driving belt that leads, and can obtain a kind of special form of implementation, and the edge zone of fiber can be controlled better or be shaped.
Better mode is that concentric is settled by the lap limit of transmission dish and bobbin.In order to utilize described advantage, the axial spacing between limit dish and the driving belt must not surpass 5mm.Limit most this spacing to be chosen as 1 to 2mm.
Other advantages are described in detail below explanation and configuration example.

Fig. 1 is a schematic diagram of producing the lap former 10 of a lap 12.This lap former is mainly used in fibrous material in further first being processed, and fiber web or cotton-wool bar are wound into volume.For example at combing process, this lap former is to be used for receiving from drafting system coming out and process finger plate, the cotton-wool bar of pressure roller or interior fiber web, and at this, the lap of producing is then delivered on the combing machine and carried out combing.When hereinafter relating to the fibrous material that is fed, for simplicity, only with this title of cotton-wool bar, but this should not be construed as limited implication.
Cotton-wool bar 14 is to be fed into lap former 10 by cotton-wool feed mechanism 16.Feed mechanism described herein is made up of arc of outlet side end.Cotton-wool bar 14 is wound up on the bobbin H as the axle center, and bobbin is around fixed axis A swivel bearing.Bobbin H is by a belt driving belt transmission.At two guide roller R1, a pendant 20 that forms between the R2, bobbin H promptly is accepted in this pendant.Situation described herein, lap 12 are to be driven by clock and watch pointer direction by driving belt 18, shown in arrow F among the figure.The pendant 20 that driving belt 18 twines lap is to enlarge along with the increase of lap 12, and wherein driving belt 18 is to give tensioning by tensioner 22 in whole rolling process.Tensioner 22 has the jockey pulley R4 of a band linear guide device 24.
Guide roller R1, R2, R3, R5, jockey pulley R4 and bobbin H are identical diameters in configuration example shown in Fig. 1.The axle of deflector roll and bobbin is parallel to each other.Be in top deflector roll R1, R2 has a vertical spacing with remaining deflector roll R5 and jockey pulley R4, and this spacing is greater than the maximum gauge of lap 12.Two deflector roll R1 of one side, the axle of R2 is in same horizontal plane, and the axle of guide roller R5 and jockey pulley R4 is in a horizontal plane on the other hand.When these deflector roll positions of representing with solid line on figure appear at the winding process termination, be that jockey pulley R4 occupies its left side terminal location, guide roller R2 is not as yet to inner rotary (guide roller R1, R3, R5 fixes), at this moment Xia Mian left side guide roller R5 misplaces to the left side with respect to top left side guide roller R2.Jockey pulley R4 is among Fig. 1 with left side terminal location shown in the solid line, and its guide roller R1 above relatively forms to the right dislocation, this moment two deflector roll R1, the level interval between the R4 is greater than the spacing between deflector roll R2 and the R5.To this, deflector roll R1, R2, R4, R5 is configured to trapezoidal, and wherein the level interval between R4 and the R5 deflector roll is just greater than the spacing between deflector roll R1 and the R2.Jockey pulley R4 occupies the terminal location on its left side in Fig. 1 roller position represented with solid line.From the left side terminal location of jockey pulley R4, the guide roller R3 of the face that is installed on it misplaces to the left side to a certain extent.The magnitude of misalignment of measuring to another roller center from the roller center is approximately identical to the radius with same diameter deflector roll R1-R5.Roller R3, the vertical interval between the R4 is pressed center distance measurement, roughly is equivalent to the diameter of roller.Can affirm that for this reason driving belt 18 does not depend on the position of roller around jockey pulley R4, remains 180 ° angle of contact.Driving belt 18 be by the transmission device that does not show in detail on the figure by being positioned at the guide roller R5 transmission on the plane, driving belt 18 promptly is stretched in this plane.Top, left side guide roller R2 is placed in the upper terminal of a turning arm 26, and this turning arm is to be contained in another terminal supporting, can be around the axle rotation of lower left guide roller R5.Dot out the keep left position of rotation on limit of turning arm 26 among Fig. 1, on this position, completely roll up lap 21 and be discharged from.
Bobbin H and two guide roller R1 around fixed axis A rotation, what the size of R2 was selected and the mutual configuration when dextrorotary turning arm 26 enters the operating position is performed such, promptly at guide roller R1, between the R2, the pendant 20 that is formed by driving belt 18 begins to use the angle of contact greater than 180 ° of minimums to surround bobbin at winding process.The extension of the pendant 20 during this initial winding process dots in Fig. 1.Jockey pulley R4 occupies the terminal location on its right side in this stage.When the rolling process, the angle of contact that pendant 20 surrounds bobbin is bigger.Jockey pulley R4 is shifted to the left, stops when it arrives the terminal location of left side shown in the solid line in lap 12 full volume backs.
Bobbin H in the middle of two lap limit dish 32,33 (Fig. 2) is suitably clamped, and the direction of arrow was taken off from avris shown in the limit dish can be gone up by figure.Limit dish 32,33 is mounted with and makes the insertable socket 36,38 of bobbin.
As can be seen from Figure 2, guide roller R1 is designed to channel shaped male and female face 44 on its circumference, and it utilizes the tooth 13 of the one-sided male and female face 9 of driving belt 18 to constitute in guiding area to traverse one of driving belt carriage direction and is rigidly connected.The male and female face 9 of the driving belt 18 shown in the profile is seen as a tooth bar shape structure from cross section.Showed three layers of outmost cotton layer 14 as an example among Fig. 2 and Fig. 3, its width exceeds the width of guide roller R1 respectively with size a in both sides, and at this moment, the lap layer is resisted against on the end face 39 of limit dish 32 and 33.
Cotton-wool bar 14 is compressed when winding process, and it can only stretch in its width like this, up to it till card on the end face 39 is tight.This is an effect of being expected by the small stretching, extension of size a, because act synergistically with lap limit dish 32,33, cotton-wool bar 14 fringe regions is compressed to a certain extent, smooth bright and clean.By between guide roller R1 and the driving belt 18 as being rigidly connected of above-mentioned suggestion, make size a remain a constant value.Do not have this lateral guide to, produce undesirable filling when driving belt can cause fringe region when avris is offset, scatter thereby divide ground that cellulose floss takes place at this intra-zone.There are many kinds of geometric form structures can be made for the selection of male and female face.It is contemplated that just the fringe region at driving belt or guide roller has just designed this male and female face.The male and female face structure can be extended to the both sides of axis MA equably or unevenly.
Fig. 4 shows another configuration example, the eyelet 34 that the fringe region of driving belt is designed to arrange one by one, and tooth 35 can mesh with eyelet, and tooth is to be distributed on the circumference of guide roller R1 by the b that spaces.Driving belt also can because of this device in the guide roller zone along lateral register.Here also can select various geometries.
Fig. 6 shows another configuration example, and promptly chain 49 is fixed on the driving belt with support 52.Here support 52 is to be fixed on the driving belt with fixture 53 (for example rivet), and connecting plate 51 is installed on the chain 49.Chain link 50 spacing in accordance with regulations is fixed on the connecting plate 51.Gear 46 is coaxially installed on the outside with guide roller R1, and its tooth 47 is engaged in each chain link 50 for avris fixes.Driving belt 18 in the guide roller R1 zone also can carry out the avris guiding with this device.Be directed in order to make driving belt when turning to, can traverse transporting direction with being rigidly connected, remaining guide roller R2, R3, R5 also can assemble this device.
Cotton-wool bar 14 is that a steering component 40 between the R2 enters in the pendant 20 in zone 42 by cotton-wool bar feeding unit 16 and through guide roller R1.In winding process, lap 12 diameters of rolling increase gradually, when it reaches a corresponding size of giving control device 28 by sensor 30 circular till.Then start discharge mechanism by this control device, the R2 that at this moment leads deflects down by turning arm 26, and lap is discharged discharge.In order to discharge lap 12, lap limit dish 32 and 33 moves laterally, and lap just can leave from its winding position.Then import a new bobbin to lap axle 20, guide roller R2 is turned back to its winding position again afterwards.The lap limit dish 32 and 33 that and then bobbin is come simultaneously clamps, and this system is ready to produce a new lap again like this.About other details that silver lap is shaped, can see from the patent specification of delivering, for example see from DE-195 39 365.
